Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes In the three months ended March 31, 2022, GM entered into a Share Purchase Agreement with SoftBank Vision Fund (AIV M2) L.P. (SoftBank), pursuant to which GM acquired SoftBank’s equity ownership stake in GM Cruise Holdings LLC (Cruise Holdings) and separately, made an additional $1.35 billion investment in Cruise in place of SoftBank. As a result, GM’s ownership in Cruise increased above the 80% threshold which allowed for inclusion of Cruise in our U.S. Federal consolidated income tax return and the release of a valuation allowance of $482 million against certain Cruise deferred tax assets. Refer to Note 16 to our condensed consolidated financial statements for additional information regarding the Share Purchase Agreement with SoftBank. In the three months ended March 31, 2022, income tax benefit of $28 million was primarily due to tax expense attributable to entities included in our effective tax rate calculation offset by the release of a valuation allowance against certain Cruise deferred tax assets that are considered realizable due to the reconsolidation of Cruise for U.S. tax purposes. The effective tax rate is lower than the applicable statutory tax rate primarily due to tax benefit related to the release of the Cruise valuation allowance. In the three months ended March 31, 2021, Income tax expense of $1.2 billion was primarily due to tax expense attributable to entities included in our effective tax rate calculation and the establishment of a valuation allowance against Cruise deferred tax assets that were considered no longer realizable. At March 31, 2022, we had $20.4 billion of net deferred tax assets consisting of net operating losses and income tax credits, capitalized research expenditures and other timing differences that are available to offset future income tax liabilities, partially offset by valuation allowances.
